| Abstract(in English) | In this paper an algorithm for extracting character strings from scene images is proposed. Most characters on scene images appear with the same color and font size at every word or text line. In our algorithm, a scene image is divided into several blocks based on edges in a color space at first. Secondly, the blobs of pixels which have the similar color are extracted by a clustering in a color space for each block. Although these blobs are correspond to characters or background patterns, after connecting them using these aspect and pitch, SVM (Support Vector Machine) on several texture features of these blobs will classify each connected blob into character or background patterns. In addition, we built extracting character pattern and OCR system which ran under picture phone. Testing with 251 images from ICDAR 2003 Text Locating Competition shows our algorithm effective. |
